Preliminary results on the transverse flow of K+ mesons from Ag+Ag collisions registered by the HADES experiment

This paper presents the preliminary results on the anisotropies of the azimuthal angle of K[Formula: see text] mesons produced in Ag+Ag collisions at a beam energy of 1.58A[Formula: see text]GeV measured by the HADES spectrometer. The transverse flow effect is measured with the harmonic coefficients of the cosine series describing the azimuthal angle distributions in the transverse momentum-rapidity phase space. The coefficients are corrected for the finite event-plane reconstruction resolution, however, occupancy effects in the detector have not yet been studied. Some indications of the K[Formula: see text] antiflow are visible in the [Formula: see text] distribution.
